In August 2007, at the close of the band's world tour in support of Stadium Arcadium (2006), the band entered a one-year hiatus, which subsequently stretched to over two years. Bassist Flea stated, "I talked everyone into it and some people were more prone to it than others. [...] I just felt like I wanted to take two years away just to really look and see if the band was something we should still be doing. Things had gotten dysfunctional and not fun."[11] During this time, Flea studied music theory at the University of Southern California,[12] drummer Chad Smith recorded and toured with hard rocksupergroupChickenfoot, whilst guitarist John Frusciante recorded and released his tenth solo album, The Empyrean. According to vocalist Anthony Kiedis, there was a collective decision "not [to] do anything Red Hot Chili Peppers-related for a minimum of one year. [...] We started in 1999, with the writing and the recording of Californication, and we didn't really stop until the tour ended last year. We were all emotionally and mentally zapped at the end of that run."[13] During the band's self-imposed hiatus, Frusciante departed from the band for a second time, stating, "there was no drama or anger involved, and the other guys were very understanding. They are supportive of my doing whatever makes me happy and that goes both ways."[14] Regarding Frusciante's departure, Flea stated, "he just didn't want to do [the Red Hot Chili Peppers] anymore. He really wanted to do what he wants to do, on his own, without having to deal with the band dynamic, our band dynamic."[15] Kiedis notes that, "John had become disenchanted with being in a touring rock band, which is completely understandable. He's a driven person in the world of music and sound, and he wanted to change gears."[16]

Following Frusciante's departure, Kiedis stated that both he and Flea, "had this intuitive feeling. We're not really done. We wanted to maintain the Red Hot Chili Peppers if we could do it in a way that upheld historically what we had accomplished. [...] There were some interesting conversations about, do we try to find someone we don't know, or maybe there is somebody right in our own backyard who is the perfect solution?"[17] Flea commented on the band's eventual return stating, "for me, the biggest thing during the time off, and what really made me want to continue doing the band, specifically after John decided he didn't want to continue, [was] I just realized, Anthony, man, he's my brother, I love him so much, and we started this band when we were kids. I wanted to keep that going, I never want to let that go."[11]

Frusciante was subsequently replaced by friend and frequent collaborator Josh Klinghoffer, who had been performing alongside the band during the final legs of the Stadium Arcadium tour. Regarding Klinghoffer's entry into the band, Smith noted, "we've known him a long time. He's super-talented, smart, handsome. He fits in perfectly, which is a good thing,"[18] and later stated: "We couldn't have asked for a better person to play music with."[19] Klinghoffer noted, "I've always been attracted to the idea of a tight-knit unit, a band of family, a brotherhood. Since my earliest memory, they always seemed like a band with a lot of love for each other."[20]

Joining the band in late 2009,[17] Klinghoffer began writing and jamming with the band on October 12;[21] the same day that friend and autobiographerBrendan Mullen died. According to Flea, "it was a poignant moment for us. It was an emotional thing."[15] Klinghoffer notes that: "It was sort of a sad hello. Everybody lost a good friend."[16]

Klinghoffer subsequently made his live debut with the band on January 29, 2010, performing a cover of the Neil Young song, "A Man Needs a Maid", at MusiCares event honouring Young.[22] Prior to the event, Chad Smith noted, "it's the first time we've played out with Josh, just the four of us, so it'll be an exciting night for him. [...] We're taking it slow. One song at a time."[23] Flea commented on Josh's impact on the band, stating "over time he really revealed himself to be just the best person we could've got. And John Frusciante's such a powerful musician and left such an imprint on our band and gave so much as a writer, as a player, a serious part of our band, that no one could ever replace John. No one's ever gonna step in and do what John did. But Josh came in and does what Josh does and does it in a beautiful way."[11]

Kiedis noted, "there is no question – this is a beginning," with Smith confirming that statement by adding, "this is a new band. Same name, but it's a new band."[17]

The album was produced by Rick Rubin; in the same studio in which the band recorded Californication, and at Shangri La.[24] The album's recording sessions took place from September 2010 to March 2011. According to Rubin, the band recorded enough material to release a second double album, following Stadium Arcadium (2006), but ultimately decided not to. Rubin notes, "it was painful not to share all of the material that we had, but we felt it would be too much. We really wanted it to be twelve songs but it ended up being fourteen just because nobody could agree on which twelve." Regarding the band's decision to work with Rubin once again, Chad Smith stated, "we have a great working relationship with him. He's been working with us for twenty years. We feel that he's the fifth Chili Pepper. He's someone that we love and trust."[19]

I'm With You was claimed to be the first ever album specially mastered to optimize digital sound quality for iTunes Store customers who purchase the album through iTunes. The album was mastered using high-resolution sourced audio.[25] Despite this, the mastering has been deemed extremely loud and over-compressed and therefore distorted, continuing the trend since One Hot Minute.[26][27]

According to drummer Chad Smith, the band "wrote a lot of songs" during ten months, from October 12, 2009 to August 2010.[19] Smith noted, "every record is a real snapshot of where we're at during that time in our lives as a band and as a people. It's always been that way."[19] Flea stated that the band wrote around 60-70 songs for the new album and writing took around nine months before they entered the studio with Rick Rubin.[28][29]

Regarding the departure of guitarist John Frusciante, and the arrival of Josh Klinghoffer, vocalist Anthony Kiedis stated, prior to the album's release, "it is always going to change the chemistry and feeling of the music when such a creative force as John Frusciante leaves. He was something unique that shaped our sound then, but now I think it's also something fresh and exciting to have a new, incredible musical mind working with us now. We are still the Red Hot Chili Peppers, but we also have to adapt and welcome new opportunities. After all, that is how we've survived all these years."[30] Producer Rick Rubin commented on Klinghoffer's addition to the band, stating, "Josh is fantastic. He played with John Frusciante for many, many years and he actually toured with the Chili Peppers before, so he's sort of part of the extended family. He's stylistically very close to John but has a completely different trip. It sounds like the Red Hot Chili Peppers that you've never heard before."[31] Flea remarked, "Josh is a very subtle musician and it's not so much about the big riff - it's more subtle, sublime, poetic texture type of playing. We’re just reacting to him, and it makes us play different, so we’re just going a different way, and it’s great. We still sound like the Red Hot Chili Peppers, but it’s really a lot different."[11][32]

Kiedis commented on the overall writing process, noting, "this album has been one of evolution. Before, some of our jams were a bit hit-and-miss. On this record, a decent number of songs were actually thought out and planned in a way we had never done before. That is, with Flea's new knowledge of music theory, we explored the writing process with a bit more precision."[30] During the band's hiatus, Flea studied musical theory classes at the University of Southern California,[12] learning piano during his tenure. According to Kiedis, Flea's piano contributions to I'm With You added "a whole new dynamic"[30] to the band's sound. According to Flea, Klinghoffer also wrote songs on piano for the album: "I started writing songs on piano for this record and Josh also wrote songs on piano, so a lot of the songs were written on the piano and then translated to [the] rock band. It has a different kind of feeling, kind of more of a liquid, poetic feeling is the best way I can describe it."[11]

According to the band, "Brendan's Death Song" was the first song written for the album, with parts of "Annie Wants a Baby", written on that same day. Album opener, "Monarchy of Roses", which is a darker song and a mixture of funk and pop was written and recorded under the working title, "Disco Sabbath".[21] Other songs like "Did I Let You Know" focus on social commentary about the planet while "Police Station" is a slow, emotional piece of music that tells a story of Kiedis running into various old friends throughout L.A, all of whom have turned into down-on-their-luck, tragic figures. Kiedis reminisces about past times with these characters over a moody, complex chord progression from Klinghoffer.[34] According to Anthony, the final song written for the album was "Even You Brutus". It was written after the band stopped writing songs and were already in the recording studio. Flea came in and played a piece on the piano that the band felt they needed to turn into a song.[35] "Dance, Dance, Dance" has been described as the most atmospheric and family-friendly song on the album.[36]

According to Flea, "life and death is a major theme of the album".[15]

However other themes in the album that have been found are; beginning of romantic relationships,[15] hardship of poverty,[15] quitting drug abuse,[15] and the dashing of dreams and wishes.[15]

According to Flea, the album is, at times, influenced by African music. Flea stated, "We've always all loved African music. Throughout our career we've played some African bits, but we never really captured it right. Josh and I tripped around Ethiopia with a group called Africa Express, which Damon Albarn organized. We saw music every night and jammed with musicians. Ethiopia is such a great country, beautiful place. So there are a couple African parts on the new songs. One is called "Did I Let You Know," which has a real African feeling, and there's another called "Ethiopia." I'm really grateful to Damon for bringing me along. It really widened my scope of humanity."[15] Chad Smith also commented on the album's African influences, stating his love of a compilation album, entitled The Afrosound of Colombia, and noting that the song, "Ethiopia", "puts a smile on my face."[37]

During a June 2011 interview with Spin magazine, Chad confirmed that controversial British artist Damien Hirst would design the album cover.[38] On July 5, 2011, the cover artwork was released through the band's mailing list. Anthony described the album's cover art by saying, "It's an image. It's art. Iconic. We didn't give it its meaning but it's clearly open to interpretation."

Flea's daughter, Clara Balzary, has been involved with taking promotional photos of the band leading up to the release of the new album. Most of the first shots of the new lineup were taken by Clara, and her photography is featured in the album artwork.

In June 2011, cryptic themed street posters and artwork of a robot with the band's logo and 8/30/11 began appearing in various places around Los Angeles. At the time it was denied by the band's management that the artwork was released by the band or the album cover however on July 14, 2011, TMZ broke the news that the artwork has been endorsed by the band to promote the global release of the new album. The artist behind the work is Mr. Brainwash. Brainwash claims that his work with the band is not finished and he will be teaming up with them on several more projects.[39]

The working title for the album was rumored to be Dr. Johnny Skinz's Disproportionately Rambunctious Polar Express Machine-Head. According to an early 2011 article in Spin Magazine, Kiedis said "[A friend] was reminiscing about one of his legendary acid trips, and told us that he had been playing a sold-out show to the planets and moons, and his number-one hit was, well, that title".[40] Two months later the working title name was denied by producer Rick Rubin and Anthony. Through his father, Anthony told fans, don't believe the rumors. There was no friend, no acid trip and it was all a lie.[41]

When it came time to decide on a title for the album, Anthony started making lists of titles. However, none of them seemed to capture the spirit of the record. He said they thought of naming it after a song on the album however Rick Rubin told him that made it seem like the band did not have enough ideas. A day before the deadline to find a title, Josh wrote down the words "I'm with you" on a piece of paper and very subtly showed it to Kiedis and the rest of the band who fell in love with the title right away. Klinghoffer said the title came to him out of nowhere and explained, "It seems pretty open, pretty apropos to where the band is, what the band's doing, how the record wants to be related to, or related with." Kiedis said, "It's open, and there's not really a negative connotation. It's inviting. The first time I heard a non-one-of-us mention it, it gave me the best feeling you could imagine. Unbeknownst to me, the news [of the album's title] had hit the radio, and some kid came up to me and he shook my hand and he said, 'I'm with you!' And I was like, 'Why are you saying that? Where did you hear that?' He said, 'I'm with you!' And then I realized that he must've heard it on the radio or something, and it was just a great feeling." This is the first album since 1989's Mother's Milk not to feature a title track.[42]

In December 2011, Q voted the album cover art as one of the best album covers of 2011.

The band's official site held a global listening party on August 22, 2011 where they streamed the entire album. Various radio stations throughout the world began playing tracks on the same date leading up to the album's release.[43] The full album was also made available to stream for free on the iTunes Store.[44]

The band kicked off a string of promotional shows and appearances starting in August 2011. On August 30, 2011, the date following the album's release in the United States, the band performed the entire album (apart from "Even You Brutus?") in sequence at a via satellite world-wide theatrical event called Red Hot Chili Peppers Live: I'm With You.

Sports channel, ESPN and many of their programs featured songs from I'm With You during various clips, segments and commercials throughout the months of August and September.[45] The NFL has also used the album's songs during football games mainly prior to commercial breaks or playing throughout the stadium during timeouts. In 2011, the U.S. version of the Simon Cowell reality show, The X Factor used "Look Around" as a theme to their earliest commercials to promote the show. The album's second single, Monarchy of Roses" was used in a Japanese car commercial for the Nissan Elgrand.[46]

In the United States, I'm with You debuted at number two on the Billboard 200 with 229,000 copies sold in its first week.[47] The album entered the UK Albums Chart at number one on the strength of 71,000 units, becoming the band's fourth number one effort in the United Kingdom.[48] With a tally of 28,000, the record opened on the Canadian Albums Chart at number two.[49] Internationally, I'm With You debuted and peaked atop the charts in over ten countries.[50]

I'm with You received mostly favorable reviews from music critics.[51] At Metacritic, which assigns a normalized rating out of 100 to reviews from mainstream critics, the album received an average score of 63, based on 35 reviews, which indicates "generally favorable reviews."[51] John Lewis of Uncut magazine released the first review of the album in said magazine's September 2011 issue. He rated the album 3 out of 5 stars in a generally favorable write-up, stating that although "listening to a playback of new RHCP album, I'm with You, one can definitely hear a John Frusciante-shaped hole in the proceedings", the album did have many great tracks. In particular, he cited the songs "Happiness Loves Company", "Even You Brutus?" and "Police Station" as some of the album's highlights. Despite all of this however, he alluded that the album lacked the overall quality of the band's material with John Frusciante, saying "Minus their star guitarist, the Chilis are a bit mild.".[61] The second review of I'm with You was written by Amy Bangs of Rock Sound. In another positive review which saw the album achieve a rating of 7 out of 10, she felt that any "drastic departure from their mixture of rock and funk is a disservice to fans", although she went on to say that tracks such as "Monarchy of Roses", "Even You Brutus?" and "Did I Let You Know" show a more experimental take on the band's trademark sound, saying that the former "layers a fast-paced dance beat and electronic instrumentation over the top of Flea's characteristic bass lines and Anthony Kiedis' unmistakable vocals." Despite this, she wrote that “There's a familiar funk-inspired sound on "Ethiopia" and "Look Around".” She also claims that new guitarist Josh Klinghoffer's playing on the album avoids the complex playing of former guitarist John Frusciante, whilst also noting his contributions on keyboard. She felt that the album was, overall, a successful continuation of their trademark sound, while also an exploration of several styles new to the band.[62]

In a similarly positive review, Q's Isaac Newton rated the album 3 stars out of 5. He hailed 'Brendan's Death Song' as the album's best track, whilst posing a question about what he interpreted as more introspective lyrics from the band on tracks such as 'Police Station' and 'Meet Me at the Corner', asking "are Red Hot Chili Peppers suffering a sudden attack of level-headedness?".[63]

Jon Dolan of Rolling Stone was also positive about the album, giving it a rating of 3.5 out of 5 stars and saying that "Josh Klinghoffer, who's worked with Beck and Gnarls Barkley, is well suited for giving old tricks new shape", describing his guitar playing as "textured" and "elusive". Dolan also acknowledged the band's influences from The Rolling Stones throughout the album by citing that the album's replacing of John Frusciante with Josh Klinghoffer could be compared to The Rolling Stones' replacing the late Brian Jones and returning to a more stripped down and basic sound formula.[64]

The most positive review so far comes from Artistdirect writer, Rick Florino who gave the album 5 stars out of 5. Florino calls I'm with You a masterpiece, the best record of their career and a rock record for the ages. Florino said 'Police Station' is the most vibrantly visceral visual that the band has ever conjured and that the song paints a vivid portrait of loneliness and failure that's as tearjerkingly infectious as 'Under the Bridge' but with another two decades of instrumental intricacy infused at heart.[65]

Diminuendo showed an affinity in the album, although expressed a dislike for the songs "Brendan's Death Song" and "Even You Brutus?", saying the tracks "[were] not so great, and just too long." He noted that "the guitar work is different, obviously, since Josh Klinghoffer filled in for Frusciante. Different, but good." Ultimately, Diminuendo surmised that the "Red Hot Chili Peppers, with or without all of its members, still rocks because the name is just synonymous with greatness,"[66] giving the album a rating in volume setting of 7 out of 11.

However, not all critics have been impressed with the album. The band's hometown newspaper, the Los Angeles Times, gave the album a pretty negative review, saying it is a mishmash, lacks a center, and way too often feels duct-taped together from various points in the band's career. Writer Randall Roberts stated that out of the 14-song album there is a good EP worth of songs and did praise the album's first single, 'The Adventures of Rain Dance Maggie' along with 'Brendan's Death Song', which he said are among the best songs of the band's career. Roberts ended his review by saying the rest of the songs are stuff that will probably sound just fine beneath NFL highlight reels but fails to gel when the volume is up and California 2011 beckons.[67]

On August 10, 2011, the album's first single, "The Adventures of Rain Dance Maggie" reached number one on the BillboardAlternative Songs chart giving them their 12th number one single. They already held the record for most number one singles at eleven and with this single extended their record. The single also reached number one on the BillboardRock Songs chart giving them their first number one on this chart which was created in 2009.[68] The single also reached number one on the Canadian Alternative chart.[citation needed]

Rolling Stone ranked "The Adventures of Rain Dance Maggie" the 50th best single in their Top 50 Singles of 2011,[70] while the Reader's Poll named I'm with You the 8th best album of year,[71] and "Brendan's Death Song" as named tenth best song of 2011.[72]

As of May 2016, I'm with You has sold 1,700,000 copies worldwide with 574,000 copies being sold in the United States.[73] By most estimates, sales for the album have been a disappointment especially compared to the band's previous album, Stadium Arcadium which went onto sell over eight million copies worldwide with two and a half million copies sold in the U.S.; currently the album is on pace to be the band's lowest selling album since signing with Warner in 1991 and lowest selling album since 1987's The Uplift Mofo Party Plan.[74]

In December 2012, the band made Forbes' World’s 25 Highest-Paid Musicians for 2012 list placing at number 19 and taking in $39 million for the album and tour to support it.[75] The tour made $33,911,873 in 2012 which was ranked 15th on Billboard's annual Top 25 Tours list.[76]

In the Spring of 2011 the band announced their first tour dates since 2007. On July 27, 2011, the band played their first show since August 2007 and their first show with Klinghoffer. The event was very private and only 300 people were allowed to attend. It was held on the lawn outside the Henry Miller Memorial Library in Big Sur, CA. The band played a mixture of new and older songs. Rick Rubin, David Fricke, Vincent Gallo and Beach Boy Al Jardine were in attendance along with many of Flea's neighbors, since his house is close to the library.[77][78] They followed this show with two more secret shows in late July. The band played festivals in Asia as a warm-up to the official tour kick off in Colombia on September 11, 2011. Following the Latin American leg, the first European leg of the tour lasted until December 2011.[79]

Flea said that he expects the tour to last "forever" while Anthony stated when talking about the new album, "I can't wait to go out and play this."[17] According to sound engineer, Dave Rat, the tour will last into 2013 and the band's schedule will be spent 3 weeks on the road and 2 weeks off throughout the tour, a plan they have followed on previous tours.[80] Percussionist, Mauro Refosco and keyboard player, Chris Warren have joined the band's touring lineup as backing musicians for the entire tour.

The band's first leg in North America in early 2012 was forced to be rescheduled until late March 2012 due to multiple foot injuries Kiedis has suffered through since the Stadium Arcadium tour. Kiedis had surgery on his foot and is expected to make a full recovery. The first U.S. leg of the tour, which includes stops in Canada, will now kick off in March 2012 and run to June with the rest of the U.S. dates being added or made up from August to November 2012.[81] During the band's first leg of the North American tour they were inducted into the Rock and Roll Hall of Fame. In March 2012, Chad Smith said the band plans to tour throughout the remainder of 2012 with dates in Australia, New Zealand and Africa scheduled for early 2013. He said if the band were to release a new album it wouldn't be until at least the end of 2013.

The tour was named 15th highest grossing tour of 2012 by Billboard on their annual Top 25 list.

The band announced that they would start releasing official bootleg live downloads of full concerts from their current tour. The shows will be available in MP3 for $9.95 and ALAC and FLAC for $12.95. Each show is available for pre-order and will be released 72 hours after the completion of each show.[82]

A two disc set titled I'm with You - Australian Tour Edition was released on January 11, 2013 exclusively in Australia to promote the band's 2013 tour dates in that country. The album contains the full studio album on one disc and eight of the outtakes from the I'm with You Sessions on a second disc.[83][84]

In August 2012, the band started to release previously unreleased songs from the I'm with You recording sessions. Nine singles featuring seventeen songs were released in total with the final being released in July 2013. Each release contained two songs featuring an a-side and a b-side and they will be available on 7" vinyl and digital download.[85] In late 2013, all 17 outtakes were released as a double LP entitled I'm Beside You. Klinghoffer confirmed that some post session work was done as late as 2013 on the songs from I'm Beside You.

According to the band, around 50 songs were recorded during the album sessions. To date, 19 remain unreleased. Of those song, Klinghoffer mentioned "Renaissance" as being one of the titles and he even has teased it live. Alternate versions of songs also exist. "Look Around" is featured on Rock Band DLC with its original intro (which was also played live). During recording process for the album, and as with every album, some of the songs had alternate working titles that were mentioned by the band in pre-release interviews. "Did I Let You Know" ("Take Me Home" and "Lagos"), "Police Station" ("Stolen Stone"), "Monarchy of Roses" ("Disco Sabbath"), "Goodbye Hooray" ("See You Around"), "Magpies on Fire" ("Magpies") and "Your Eyes Girl" ("Mormon Lover"). "Did I Let You Know" also had the suffix '(This I Know)' during some of the band's interviews.[86]
